3 Claims.

The present application is a division of my copending application,Serial No. 432,014, filed February 23, 1942, now Patent No. 2,390,104granted February 4, 1945.

In cabinets in which ice is used for cooling or deliquescent chemicalsfor dehydrating air, or both, it is desirable to dampen the drip andsplash to have quiet operation. Also, where such cabinets are movedaround in a room or used in moving conveyances, it is advisable thatsome precaution be taken to prevent spilling and splashing of the wastewater and waste chemical solution. Furthermore, evaporation of wastestored water into the air stream should be prevented.

According to the present invention splash prevention, drip noises andevaporation of waste water have all been effectively controlled throughimprovements in waste tank construction in which the surface issubstantially sealed from the air stream and a floating raft is employedto prevent splash. A screen carried by the raft reduces splash and dripnoises.

Thus one object of the present invention is to provide a portablecabinet of the type described in which a waste tank is provided withsplash preventing means.

Another object is to provide an improved waste tank or device of thecharacter described in which the air stream is substantially sealed fromthe surface of the waste tank to reduce evaporation to a minimum.

Another object is to provide a portable cabinet of the type developed inwhich drip and splash noises have been materially reduced.

These and other objects and advantages residing in the combination,construction and arrangement of parts will be more fully understood froma consideration of the following specification and claims.

In the drawing,

Fig. 1 is a vertical section through the cabinet and its interiorstructure,

Fig. 2 is a sectional view taken on line II-II of Fig. 1, and

Fig. 3 is a sectional view taken on line III-III of Fig. 1.

In the illustrated embodiment, the portable cabinet It) has an openingl2 in the bottom l4 for the upward flow of air around the waste tank H5.The air passes between perforated trays l8 and into indirect contactwith the ice in the ice container 20 and with the chemical dehydrant inthe dehydrating case 22. For a more specific disclosure of the air flow,reference is made to my aforesaid copending application.

Ice water from the ice container 20 drips through openings 24 upon thetrays l8 and is cascaded from one tray to the next through openings 26.From the lowest tray ill the waste ice water is discharged upon thecover plate 28 which extends over the entire tank I6. Holes 30 in theplate 28 permit the waste ice water to drip through to engage, withoutappreciable drip or splash noises, with the close meshed screen 32supported on the floating raft 34. Brackets 36 limit the upward movementof the raft 34. The level in the tank [6 is maintained'at this sameheight by the overflow pipe 38. Openings in the raft 34 are indicated at40 and 42 and permit the waste ice water to pass through the raft andinto the overflow 38.

Waste chemical solution from the dehydrator case 22 drips upon thescreen 44 located beneath the case 22 and supported upon the plate 28.The screen 44 reduces drip and splash noises in the same manner on thescreen 32.

Casters 46 support the cabinet 10 for movement. The raft 34 floated uponthe surface of the tank IE will permit such movement without fear ofsplashing the contents of the tank. Similar results will be obtainedwhen the unit 10 is installed in moving vehicles, such as trucks, buses,trains and the like. In practice, accumulation of waste in the tank "5will be drawn out the drain 48 from time to time to avoid use of theoverflow 38.

Iclaim:

1. An air conditioning apparatus of portable construction and adapted tobe moved about while in service, comprising an air conditioningunit, awaste tank supported as a unit in the apparatus and movable therewith, adischarge for waste liquid flowing by gravity from said air conditioningunit, an intake in said tank for waste liquid from said discharge, andan anti-splash and silencing means located in said tank in verticalalignment with said discharge and said intake to silence the liquiddischarged in said tank and to minimize splashing of waste liquid insaid tank outwardly through such intake, against the normal flow ofdischarge liquid, upon movement of said apparatus in service.

2. An air conditioning apparatus as defined'in claim 1 in which saidanti-splash and silencing means takes the form of a floating raftapproximating the. surface area of waste liquid in said tan y 3.-An airconditioning apparatus, portable in construction to permit moving itabout while in service, comprising an air conditioning unit, a

waste liquid cascading structure below said unit, a

Waste tank below said cascading structure of open type construction; afloating raft in said tank, approximating surface area of the liquidtherein to substantially'separate the surface of the liquid from any airstream between said tank and said cascading structure.
